Abstract

The redundancy number is usually used as the internal reliability measure. It is  commonly stated in literature that the value of redundancy number ranges  between zero and one. This study, however, indicates that the redundancy number  may be beyond that range for correlated observations. Therefore, the internal  reliability can not correctly be indicated by the redundancy number. A new  suitable internal reliability measure is discussed thoroughly.
Finally, three numerical examples representing different surveying problems such  as, vertical and horizontal geodetic networks as well as theodolite angle  observations were given in order to illustrate the app ication land the efficiency or  the proposed reliability measure.
